@2pcsofcandy: perhaps her marks are not glowing because she's finally found a way to get around her dark deal with the demons, or at least one of them? After all, that IS why she's in Innistrad, to hunt down, or find a weapon to kill one of the three demons ruling her. If I'm not mistaken, Griselbrand, the demon who killed Avacyn, is one of the demons Liliana had a pact with. Can anyone confirm this?

Or alternatively, her deal with Nicol Bolas is overriding the demon magic... After all, Bolas is more powerful than the three demons combined. (see novel Test of Metal for more on Liliana's deal with Bolas)

It's really a shame that her Innistrad promotional art is better (IMO) than her card art. Not to criticize this art, which fits Liliana almost perfectly -- it's just has a bit too much of that CG look to it.

I have made a deck that already takes advantage of her. I can kick of her ultimate mulitple times in game just for the fact BW Decks are really good at control. Mirran Cruaders and Phyrexian crusaders with her are really mean which is another feature to combo with her but I really like the fact that I have my play set of her. But I still have to admit she is really expensive at the moment for most people to use so she will either pull a gideon or a Jace 2.0 and start out expensive and go down or just stay expensive.
